问题 The artificial nose can be used to detect drugs and water contamination.
The word "logged" (Line 5, Para. 7) most probably means "entered".
选项 A、Right
B、Wrong
C、Not mentioned
答案A
解析 文中第七段提到感受器的工作原理。化学物质蒸发进入空气后又随空气一同吸入感受器，化学物质进入感受器的表面，并使流经机器的电流发生变化。电流被输入电脑后，电脑会根据不同电流识别物体的气味。因此根据上下文，可以推断这里的logged表示“输入，进入”，故选A。
